Effect of stress state on graphitization behavior of diamond under high pressure and high temperature
TL;DR: In this article , the graphitization behavior of diamond powder under non-hydrostatic (pure diamond powder) and quasi-hydrogen (mixed powder of diamond and sodium chloride) compression was quantitatively studied by analyzing the X-ray diffraction peaks' area of treated samples.

Phase-pure ST12 Ge bulks through secondary pressure induced phase transition
TL;DR: In this article , a large pure bulk sample of metastable germanium (ST12 Ge) was synthesized through secondary pressure induced phase transition, and the structure and purity of the sample were characterized via a combination of powder X-ray diffraction, Raman scattering, and Xray photoelectron spectroscopy.

A two-phase ultrafine-grained NbMoTaWV refractory high entropy alloy with prominent compressive properties
TL;DR: A NbMoTaWV high entropy alloy (HEA) was fabricated by mechanical alloying (MA) and spark plasma sintering (SPS), which exhibited a compressive yielding strength of 2785 MPa, compressive strength (σ max ) of 3661 MPa and strain to failure (ε f ) of 16.2% at room temperature as discussed by the authors .
Graphite /diamond transformation mechanism under the action of iron-based catalyst
TL;DR: Although it has been near 70 years since iron-based catalyst was used to synthesize diamond from graphite at high pressure and high temperature (HPHT), the graphite to diamond transformation mechanism still works as discussed by the authors .
